remove comment about the bug... I don't remeber what it was...
It may be an issue w/ using awk which is in /usr (and isn't always
present), or another issue...

filedesc: just free old tables without altering the list which is freed anyway

No functional changes.
filedesc: avoid taking fdesc_mtx when not necessary in fddrop

No functional changes.
Add sysctl kern.proc.cwd

It returns only current working directory of given process which saves a lot of
overhead over kern.proc.filedesc if given proc has a lot of open fds.
